FoRR took to the river on Saturday, January 15 to monitor at three sites along the Reedy River! Sites #4 and #5 were monitored by our board member on Friday, January 14. Our sites include the following:
The pH and conductivity results this month were consistent with our findings in December at all five of our reported sites.
The dissolved oxygen (DO) for all sites increased noticeably by an average of 0.5 mg/L due to the much lower water temperatures this month. This happens because as water temperatures decrease, water's capacity for dissolved oxygen increases. The increased dissolved oxygen levels are further sustained by the lowered winter metabolisms of aquatic animals. As activity levels drop for water-dwelling animals, less oxygen is pulled from the water to be used by these organisms.
Bacteria levels decreased noticeably at all sites except for Falls Park, also due to January's much lower water temperatures. Contrary to what we would usually say, the increased bacteria count in Falls Park comes as a relief this month because it indicates a return to a healthy bacteria sample. If you'll recall last month's bacteria counts for Falls Park, our bacteria petrifilm results were alarmingly blank. We have been working with local officials to report and keep a close eye on this issue, but unfortunately have not yet discovered the cause of last month's odd findings. The bacteria count of 133.3 CFU/100mL is well within state standards and is not cause for concern. The remaining four sites all had bacteria levels of 100 CFU/100mL or lower for the month of January. We expect to see these counts stay relatively low through the cooler months and will likely see an increase once warmer temperatures return.
We have included the SC State Standards below for comparison to our results.
